histogram-like plot with two variables

Hi, I want to plot a binomial propability distribution. I know how to generate the data; x <- seq(from=0, to=14, by=1) y <- dbinom(x, 14, 0.7, log = FALSE) but what I don't know is how to plot this within a histogram like plot. Because the histogram function only accepts one variable. Is there a way to get the look of "hist()" with two variables? I tried: plot(x,y, type="h") but the bars are very thin -is there a way to define the width?
You could use barplot(): barplot(y,names=x) You could also do it with plot.histogram, but it's trickier, because it's designed for continuous data. For example, dat <- hist(x, plot=FALSE, breaks=c(-1,x)+0.5) dat$density <- y plot(dat, freq=FALSE) Duncan Murdoch
